Question for you all regarding my B2650. Was snowblowing again today here in northern Michigan, just a few inches of light fluffy snow. About 15 degrees F. About 45 minutes in, and on my last pass down the driveway, all of a sudden I started blowing very black smoke out the exhaust and lost power. As soon as I backed off, the smoke disappeared and everything appeared to go back to normal/idle. I slowly resumed and things behaved normally for a short while but then again got the same smoke/power loss. So I eased it to its parking spot and started to take a look under the hood. It appeared to me that the air intake pipe was deformed/collapsed, and restricting incoming air flow. There was no obvious blockage that I could see, but with the engine running it definitely wasn't "round". After shutting the engine down, it appeared to go back to what I recall as being a more normal shape. I took pictures to try and show these two scenarios.
Am I on the right track here as a possible root cause of my issues, or way off base? It seems to me the lack of air would cause the engine bogging down and black smoke. Any reason why I would be seeing this deformation? I've run in colder temperatures than this and not had a problem before.
Also, is the air cleaner body supposed to be clamped down? Mine is just sitting semi-loose in the U-bracket.....but I honestly don't recall if that is how it has always been, or if maybe a clamp has fallen off somehow/sometime. Maybe this movement is causing the pipe collapsing?!?
Any thoughts/comments would be greatly appreciated. Happy to take more photos and provide more information if it would be useful.
